backstepping
说明： The objective is to present a nonlinear approach to design a suitable controller system for the photovoltaic (PV) single-phase grid-connected system. The system structure includes a PV generator, Boost converter, and DC-AC inverter coupled to grid network. A backstepping controller is developed to extract maximum point power tracking (MPPT), to regulate the DC bus voltage, and to generate a sinusoidal current into the grid in phase with grid voltage in order to achieve unity power factor. The stability of the control algorithm is demonstrated by tools of Lyapunov analysis. Simulations show that the proposed controller system completely accomplishes listed aims even under atmospheric conditions variation. Theperformance of the proposed controller has been validated by numerical simulation in MATLAB SIMULINK(The objective is to present a nonlinear approach to design a suitable controller system for the photovoltaic (PV) single-phase grid-connected system.

数据结构C语言版
说明： 《数据结构》这门课程是信息与计算科学专业中一门重要的专业基础课程。当用计算机来解决实际问题时，就要涉及到数据的表示及数据的处理，而数据表示及数据处理正是数据结构课程的主要研究对象，通过这两方面内容的学习，为后续课程，特别是软件方面的课程打下了厚实的知识基础，同时也提供了必要的技能训练。我们主要学习的数据结构包括队列、堆、栈、链表、树和图等。通常情况下，精心选择合适的数据结构可以带来更高的存储效率，因此，数据结构课程在计算机应用专业中具有举足轻重的作用。(Data Structure is an important basic course in information and computing science. When using computers to solve practical problems, it is necessary to involve data representation and data processing, and data representation and data processing are the main research objects of data structure course. Through the study of these two aspects, it lays a solid knowledge foundation for follow-up courses, especially for software courses, at the same time. Necessary skill training is provided. The main data structures we learn include queues, heaps, stacks, linked lists, trees and graphs. Usually, choosing the right data structure carefully can bring about higher storage efficiency. Therefore, the course of data structure plays an important role in computer application specialty.)
